SET

Syntax

SET key value [EX seconds | PX milliseconds] [EXAT timestamp | PXAT timestamp] [XX | NX] [KEEPTTL]

SET puts or updates an existing value for a key.

SET stores the value as its native type - be it int or string. SET supports the following options:

• EX seconds: set the expiration time in seconds
• PX milliseconds: set the expiration time in milliseconds
• EXAT timestamp: set the expiration time in seconds since epoch
• PXAT timestamp: set the expiration time in milliseconds since epoch
• XX: only set the key if it already exists
• NX: only set the key if it does not already exist
• KEEPTTL: keep the existing TTL of the key even if some expiration param like EX, etc is provided

Returns “OK” if the SET operation was successful.
